The flood of tools and frameworks in the front-end development world caused both the developers and their employers to lose sight of the things that really matter - software craftsmanship. It’s demand for Angular over TDD, SASS over SOLID. This loss of focus from the essentials is in the long run damaging and sadly - it is all self-inflicted. In this talk we will go over the long-term effects and explore solutions.
How i acheived a pretty good google page speed insights scoreMatt Bailey
Last year I decided to check out my own personal site in Google PageSpeed Insights. Even though it’s only a simple static flat-file site, Google didn’t give it a very good score. I decided to see if things could be improved. This presentation covers what I discovered, and what I was able to do about it.
Let’s talk about what Microsoft has given us for building ambitious, real-world Windows 8 apps in HTML5 and JavaScript—but also what’s missing, and how we can fill in the gaps.

xPad - Building Simple Tablet OS with Gtk/WebKitPing-Hsun Chen
Web is becoming the new graphic library, based on the success of xPUD project, we make it further by adding following components: 1) WebKit-based browser with finger scrolling and dobule-tap zooming function, 2) A BPMF-friendly virtual keyboard integrated with SCIM input method and 3) Touch-enhanced user interface based on xPUD’s plate framework. By using simple software stack, we’re pretty confident that xPad could be an alternative of MeeGo or Android as a lightweight and easily customizable tablet OS.
Highlights technologies in ELMSLN that are rather unique; namely spoken interface technology, conversational UIs, and why we all should standardize on web component technology for front end development to increase accessibility while lowering barriers to content production.
Are you scared by JavaScript? Have you used JQuery but struggle with adding interactive features to your web page? This talk will help you understand how to use JavaScript effectively in your existing web pages and PHP applications. This talk will explore different ways to write and structure your JavaScript code and introduce the model-view-view model pattern as a complement to the model view controller pattern often used in PHP.
Slides from my last presentation at the Cape Town Meteor meetup, on optimising the UI, specifically for Hybrid apps and for Meteor JS hybrid apps.
The main thrust is really more about design patterns, and carefully controlling data management in your mobile app, with great examples of these patterns out in the real world.

Measure and Increase Developer Productivity with Help of Serverless at JCON 2...Vadym Kazulkin
The goal of Serverless is to focus on writing the code that delivers business value and offload everything else to your trusted partners (like Cloud providers or SaaS vendors). You want to iterate quickly and today’s code quickly becomes tomorrow’s technical debt. In this talk we will show why Serverless adoption increases the developer productivity and how to measure it. We will also go through AWS Serverless architectures where you only glue together different Serverless managed services relying solely on configuration, minimizing the amount of the code written.
There are tons of awesome new tools produced by terrific companies and developers that get everyone excited about using their fancy new tool-set by essentially starting from scratch. This talk is not about using a fancy new framework and rewriting your entire application. As a developer who has spent the majority of his time working in legacy codebases where the first commits pre-date jQuery, it's hard not to get wrapped up in the "I want to rewrite the whole app with X" mentality. But in reality, time constraints or just the legacy framework you're building your apps with doesn't allow for that. Or, more realistically, it just needs to work and there is no business case for a rewrite. What this talk will show you how you can still enhance your front-end operation within an existing legacy codebase. I'll talk about first steps to modularizing a monolith, or simply taking a portion of a legacy app and modernizing it with a new toolset. This not only helps you as a developer to succeed with new tools, it makes you feel like you aren't being left behind in the modern world. Whether you're using legacy jQuery, or just some crammed together JavaScript, you shouldn't lose the ability to modernize your application, just because you can't buy in 100% to a modern framework.
Tips on how to break apart your monolithic JavaScript
Building an extension method to modularize your application
Creating backcompat methods for legacy code modernization
Using a modern framework for a portion of your app, and integrating that with your existing code.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
Advanced Flow Concepts Every Developer Should KnowPeter Caitens
Tim Combridge from Sensible Giraffe and Salesforce Ben presents some important tips that all developers should know when dealing with Flows in Salesforce.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

• ClojureScript skeptics
11. Top-down vs bottom-up
design
https://en.wikipedia.org/wiki/Top-down_and_bottom-up_design
A top-down approach is essentially the breaking down of a system to gain insight into
its compositional sub-systems. Top down approach starts with the big picture. It breaks
down from there into smaller segments.
A bottom-up approach is the piecing together of systems to give rise to more complex
systems, thus making the original systems sub-systems of the emergent system.
Bottom-up processing is a type of information processing based on incoming data from
the environment to form a perception.
12. Top-down vs bottom-up
design
• Web design: visual, wire-frames, big picture
• Clojure design: data, data, data

13. JavaScript vs ClojureScript
An observation
High-level language characteristics (permissiveness, expressiveness, design approach)
permeate the development ecosystem
14. The project
• Browser-based single page web app
• Not necessarily optimized for mobile, but should still be
usable
• Multiple data sources: HTTP APIs, WebSockets
16. Why do we need a framework?

17. re-frame
• Data oriented design. Events are data. Effects are data.
DOM is data. The functions which transform data are
registered and looked up via data.
• Uses reagent: “minimalistic interface between
ClojureScript and React”
• Hiccup-like syntax for describing UI
